The PvP trinkets are rewards in the honor system. They can be used to prevent or remove movement impairing effects. Higher-level trinkets, with additional benefits, have been added with the expansions.
Trinket Effects by Class
The original trinkets (Insignia of the Alliance/Horde) have a class requirement, but the trinkets for all classes are identical. In the past, each class's trinket countered different effects.
All classic World of Warcraft trinkets had a 5 minute cooldown and dispelled up to three forms of CC from the user. They were usable while under the effects of the CC, even if the CC otherwise prevented trinket use.
The following table lists which form of CC each classes' trinket neutralized. Notice trinkets did not provide immunity; they only reactively dispelled already existing effects.
- Patch 2.1.2 (2007-06-19): PvP Trinkets: Insignia of the Alliance, Insignia of the Horde, Medallion of the Alliance, and Medallion of the Horde have all been redesigned. The trinkets for all classes now have the same effect: Dispels all Movement impairing effects and all effects that cause loss of control of your character.
- Patch 2.3.0 (2007-11-13): PvP Trinkets: Insignia of the Alliance, Insignia of the Horde, Medallion of the Alliance, and Medallion of the Horde now clear the debuff from Judgement of Justice.
